What Are Smart Contracts? Beginners Guide For 2020

Bitcoin was the first major Blockchain application and since then most of us have come to a basic understanding of how Blockchain works. However, over the years, this technology has been rapidly growing to include other applications that can be used for myriad purposes and one such Blockchain application that has become quite popular in recent times is Ethereum, which is used to create Smart Contracts.
At Siddhatech, we offer a comprehensive Smart Contract development services. As such, in this post we’ll take a look at; what is a Smart Contract, how do Smart Contracts work, what are its benefits and the various areas where we can make use of Smart Contracts. So, let’s get started to see how Blockchain Smart Contracts help individuals and businesses.

A] What Are Smart Contracts?

In simple words, Smart Contracts are a set of computer code (protocols) that runs on the Blockchain technology and comprises of explicit terms & conditions (pre-defined rules) that are established by the consent of the involved parties. Smart Contracts helps to verify, enforce & execute digital transactions in a credible way without the involvement of third parties. This enforces transparency in all dealings, be it the exchange of money, shares, assets, property or anything of value.
A perfect example of Blockchain Smart Contracts is when you require to obtain a document of proof from the court of law. In a traditional scenario, you’d need to first hire a lawyer, pay them and then wait for the document to be given to you. But, with Smart Contracts, you’d be able to eliminate the need for a lawyer, as all you need to do to obtain a document is run the process with Smart Contracts, pay for it and get the document you want.
Furthermore, unlike traditional contracts that just defines the rules & penalties of an agreement, Smart Contracts take this a step forward by automatically enforcing/executing the said rules and obligations. Thus, greatly reducing the risk of fraud and scam.

B] How Do Smart Contracts Work?

Smart Contract is a Blockchain application, created with the help of Ethereum, which is a popular Blockchain platform. As stated above, just like a standard legal contract (on paper) that outlines the term of the agreement between two individuals or organizations, Smart Contracts does the same albeit it uses programming languages such as Solidity, Python or GoLang.
It works on a condition-based principle IF-WHEN-THEN and one of the classic Ethereum Smart Contract examples is when buying a property.
Here, the involved parties can set conditions like;
IF/WHEN the X party transfers the property on my name, THEN I’ll pay the sum of money agreed upon. Or IF/WHEN I pay the sum of money agreed upon, THEN the X party will transfer the property on my name.
There is no limit to the conditions/terms you can include in your Smart Contracts. And, it’s only when these set conditions are successfully met, the Smart Contracts would execute and validate your transaction.
Moreover, since these Contracts are stored in a distributed system, both parties can interact with each other in real-time without the involvement of a third-party. This would save a considerable amount of time and money. In addition, these encrypted contracts are stored in a decentralized ledger which ensures that it can’t be deleted, thus eliminating the chance of fraud. It also offers the involved parties the option of anonymity if that’s what they require.

C] What Are the Advantages of Smart Contracts?

Now that you know the Smart Contract definition and how Smart Contracts Blockchain application work, here is a quick look at the benefits of Smart Contracts you can obtain by shifting to this digital platform from the traditional one.


Since Blockchain Smart Contracts are a self-executing system, it needs to be precise or it might result in an error while executing. This ensures high accuracy. Also, by shifting to Smart Contracts, you’d be able to prevent human errors that come from manually filling out forms.


distributed network that works online, Smart Contracts eliminate the need of manually processing each document. This speeds up the execution process, which not only helps save time but also results in quicker decision making.


All terms and conditions included in a Smart Contract are thoroughly checked and agreed upon by all involved parties before the contract is coded. This ensures total transparency at all times. It also eliminates any dispute that may arise later on.


Without the need to involve any third-party, middlemen or intermediary, individuals and business organizations would be able to significantly reduce operational and transactional costs. Thus, saving a lot of money in return.


Greater accuracy, speed and security ensures that all transaction processes get done at a faster rate. This improves time efficiency, enabling you to complete high-value projects swiftly.


Smart Contracts offer the highest level of safety standards as it makes use of the best-in-class data encrypted technology. This prevents hacking and offers protection from all threats.

Paper Free

Smart Contracts are also eco-friendly, as by going digital you’d be able to reduce the use of paper, thus actively contributing to the ‘go-green’ movement.

Data Storage

Smart Contracts Blockchain application offers easy storage & backup feature that ensures all records of your contracts are safely stored and can be accessed anytime you want. This prevents data loss and in case the data does get lost (which is very very rare) it offers you a simple restore option.


Since there is no way to delete or alter information in Smart Contracts once it’s encrypted, it fosters a higher level of trust between the concerned parties. There is also transparency and easy access to all records at all times as it is stored on a distributed ledger, which helps to further encourage confidence between all.

Clear Communication

With Smart Contracts, you need to be specific and detailed while establishing terms and conditions. This leaves little room for misinterpretation at a later stage. Thus, helping you forge an agreement based on a clear and direct communication.

D] What Are Smart Contracts Used For?

Smart Contracts Blockchain application can be used for varied purposes by individuals, business organizations and for the Internet of Things (IoT). Mentioned below are a few areas where Smart Contracts are currently being used for.

1. Smart Contracts Applications for Healthcare

The number #1 concern in the healthcare sector is the misuse of patients information. Since most of the clinical data is maintained on paper, private health records are often vulnerable to theft. Thus, here, Smart Contracts can be a valuable aid as it will not only ensure complete security & integrity of all clinical data but it will also make sure that no third-party has access to these private records.
Also, maintaining the numerous healthcare-related records can be cumbersome leading to administrative inefficiency. As such, with Smart Contracts, this issue would also be resolved as it facilitates the easy organization of general healthcare management. This includes the supervision of all healthcare supplies and drugs to ensure there is no transgression. It will also take care of regulation, compliance and testing needs, limiting the need for any third-party involvement and human error.
